In the first linky - the TR7/TR8 brakes - the discs in the photo appear to have only 4 stud holes, when you will need 5 for a wedge hub. Don't know about the calipers.
Don't think the first ones will work as it says in the description that the mounting holes have been modified. The second ones look OK but as already said you will need a bigger spacer kit. Cheers Steve
